UPDATE: More on injuries to SF Giants’ Casilla and Pagan

UPDATE, 7:10 p.m.: Indeed, Santiago Casilla has a cyst in his right knee causing pain and is not expected to pitch for a couple of days. The Giants had the right-hander take an MRI exam late Wednesday afternoon and decided not to place him on the DL. They could have done so and recalled Jean Machi, but do not see the injury as that serious.

Manager Bruce Bochy said Angel Pagan’s adductor injury is less worrisome than a hamstring strain It affects the center fielder only when he swings the bat, not when he runs, so he can play as long as pain tolerance allows.

“There’s always a risk making any injury worse,” Bochy said, “but the fact that it’s not the hamstring makes you feel a little better.”

ORIGINAL POST: Angel Pagan returns after a day off following an MRI that revealed a strained right adductor muscle, which is near the hamstring but not the hamstring.

There’s no official word yet on Santiago Casilla (knee), but his name appears on the lineup sheet in the clubhouse as an available reliever. That doesn’t mean he really is available, but there is no replacement listed. We’ll get the word soon on a noon doctor visit that he had, but Janie McCauley of AP just quoted Bochy as saying he has a cyst in his knee that the team knew about last year, and he “may need a couple of days to let it calm down.”
